They are mostly able to be sent through social networking sites and blogs. Like many things on the internet, memes can go viral so fast they are not even checked to be true. This article "Tweety profs offer political smear-meme "truthiness" ratings" by Lewis Page looks at a group of professors from Indiana who designed a project that's mission is to stop spam meme's and rate the truthiness of a meme for people to legitimitize their page ranking. They focus specifically on political internet memes, as the spread of these can have a great influence and impact on voters, before they are even known to be valid. The program uses twitter to check for somethings 'truthyness' by tallying up votes from users who vote it to be 'truthy' or not on suspicious memes.
